Why is a joint tenancy considered a unique form of ownership?

A joint tenancy is considered a unique form of ownership primarily because all owners have equal shares and rights to the property. This means that each tenant in a joint tenancy has an equal interest in the property, and upon the death of one owner, their share automatically passes to the surviving owners rather than being distributed according to a will or through probate. This feature is known as the right of survivorship, which distinguishes joint tenancy from other forms of ownership, such as tenancy in common, where shares can be unequal and do not automatically transfer to the other co-owners upon death.

Moreover, the requirement that all joint tenants acquire their interest at the same time and through the same deed reinforces the uniqueness of this ownership structure, ensuring that it embodies a clear and equal relationship among the owners. This characteristic supports seamless succession and rights within the ownership structure.
